Alpha Microphone

The Eigenharp Alpha has a high quality microphone input that can you use with a variety of microphones of different types, Dynamic, Electret (10V phantom power) and Condenser (48V phantom power).

For those that do not wish to wire their own microphones, we sell a high quality cardioid electret condenser by DPA (a leading microphone manufacturer), pre-wired with a short cable, the correct LEMO connector and a special mounting clip made from machined aluminium that clamps to a standard Eigenharp breath pipe mouthpiece. This microphone comes with a shock mounting, which you will find reduces instrument handling noise enormously. If you want to look up he specification on the DPA site, it's a DPA4080. We tested quite a few microphones and this is the one that was the best sounding for vocals, unobtrusive in appearance and well mechanically isolated of them all.

For those that wish to connect their own microphones we have produced a white paper about how to do it - Alpha Microphone Wiring. Please note that we do not provide support for this option or assistance with wiring your own microphone, this is provided for informational purposes only. The supported microphone for the Alpha is the one we sell in out store.

For those that wish to use their own microphones, you are strongly advised not to attach it to the instrument without some kind of mechanical shock isolation as the noise of keys being played is otherwise very annoying.
